    TestFilter

    Filters features by test conditions to one or more output ports.

    This transformer is equivalent to a connected string ofTestertransformers, and can be used to reduce a workspace that is filled with Testers.

    A test condition consists of one or more test clauses and a specified comparison method (AND, OR, or COMPOSITE).

    Output Ports

    Closed

    The feature is output via theport if the feature does not satisfy any of the test conditions. The name of this port can be changed by editing the parameters.

    You can also specify your own output port names as described in step 4 under Port Definitions below.

    Parameters

    ClosedPort Definitions
    1. Double click a blank row in the table (or select the row and click the Edit Conditions button).
    2. Specify the Test Conditions. These are described in detail in theTestertransformer.
    3. Click OK to close the window and add the test condition to the TestFilter.
    4. Initially, the test condition will appear in both the Test Conditions and the Output Port columns. You can edit the Output Port field to specify your own output port name. Multiple test conditions can output to the same output port if the port name is the same.

    Repeat these steps for each test condition that you want to add to the TestFilter. The buttons on the side of the dialog box allow you to add and remove rows from the table, and set the order in which to perform the tests:

    Unfiltered Port Name

    The feature is output via this port if the feature does not satisfy any of the test conditions. By default, the port is named ‘’.

    • See theTesterfor more information on test conditions.

    Editing Transformer Parameters

    Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, clickbeside the applicable parameter.
